IMPRQVEMENT IN HYDRAULIC APPARATUS.

The Schedule referred to in these Letters Patent and making part of thesame.

To all whom 'it may concern.-

Be it known that I, NICHOLAS NOLAN, of the city of New York, in thecounty and State of New York, have invented a new and improved HydraulicApparatus; and I do hereby declare that the following is a full, clear,and exact description thereof, which will lenable others Skilled in theart to make and use the same',` reference being had to the accompanyingdrawing forming part of this specification.

Theidrawing represents a side view, )artly in Section, of my invention.l .The object of this invention is to provide means for elevating,without additional power, water or otherv liquid to .a 'greater heightthan at 4which it has its original level.l

,The invention consists in the introduction to a vertical water-'pipe ofa self-acting siphon,whereby the desiredresult is obtained. i'

' The invention -is chiefly applicable to buildings which have somestories higher than the reservoir from which their water supply istaken.

- A in lthe, drawing represents the supplyppe,the end a being shown onthe level of the reservoir from which the water is taken.

From this level the pipe A extends downward a suitable dist-ance in thearm b, and is then carried horizout-ally at c. f

From c the pipe A extends up again to d, until it reaches a vessel, B,which is labout on a level with a.

From the lower part of the vessel B projects upward a pipe, C, which isalmost, but not quite, as long as the arms b or d.

A Siphon-pipe, I), having a Stop-cook, e, near its lower end, connect-sthe arm c with the vessel B, as Shown.

The cock e being closed, the water/will pass from o intol), c, and d,iiniling its level in the vessel B.

.Lhclsiphon will contain air, which is confined by the cock e at onecud, and the water in B at the other end.

In this position the water can be drawn from 'the parts b, c, or d, atwill, and will'always be replaced.

When, however, water is to be taken from the upper pipe C, the cock ennst be opened then the water from the reservoir will rush into theSiphon D, and will force the air which was formerly confined thereininto the vessel B. l

The upward pressure upon the column of water in d causes a check-valve,g, at the lower part of cl to be closed. Y

rlhe air which was confined in the pipe D will force the water that wasiiirmerly contained in the vessel B out through the pipe C. Only lwhenthe air in B reaches low enough to be in line with the lower end of thepipe C will it escape. Thus a column of water, equal in extent to thecolumn of air confined in the Siphon, can be elevated beyond the waterline.

In order to increase the elevating capacit-y, an en'- larged chamber, E,is or may be formed on the Siphon.

The bottom oi' the vessel B is inclined, so as to bring the end of thepipe C as low as possible.

\Vhenal1 the air has been driven from the pipe D, the water is withdrawnfrom the loweiend of the Same through a faucet l1.

At thc upper end of the pipe D is arranged a valve' or oat, i, whichwill be closed by water, but not by air. Thus, all the water can bedrawn from I), as

none can enter the upper end.

Should the air have escaped from the vessel B through C, the vacuum in Dwill be filled by air drawn in through a self-acting valve, j.

As soon as the pipe'D is again filled with air,` the elevating processcan be again carried on.

Within the pipe O is arranged a valve, I, which will prevent wat-er oncein C from flowing back into-B.

Having thus described my invention,

I claim as new and desire to secure by LettersA Patent- The U-shapedsupply-pipe A, having valve g, and a Siphon, I), having faucet-valvesandcock, as described, combined with a vessel, B, and valvedischargepipe G, all relatively arranged as and for `the purposedescribed. ,A

NICHOLAS NOLAN.
